Check Out These Ssseriously Cool Banded Sea Krait Facts

Banded sea krait facts are very interesting to read.

Do you like reading about various snakes or kraits? Then these banded sea kraits or yellow-lipped sea krait (Laticauda colubrina) facts will be very interesting to you.

These sea kraits aren't true sea snakes as they spend almost half of their life on land as well as in the waters of the Indian and Pacific oceans and return to the islands in Southeast Asia where they are enjoyed as a culinary seafood dish in a few countries. These subcylindrical sea kraits have black stripes all over their body and a unique yellow lip that extends over the head to their eyelids. They also have well-developed eyesight for nocturnal hunting. The yellow lip gives them their popular name, the yellow-lipped sea krait. Their smooth streamlined body with a flattened paddle-shaped tail makes them skilled swimmers, allowing them to swim forwards and backward and ambush their prey with a surprise attack. However, these sea snakes are skilled hunters and love preying on moray eels and conger eels. These sea kraits are extremely venomous, and in some cases their neurotoxic venom can even cause death, paralysis to the brain and body, and cardiac arrest among other problems. They also have a paddle-like tail and succulent lungs to swim underwater efficiently.

How do they reproduce?

The banded sea krait is not true a sea snake and they are oviparous, meaning a female lays eggs that develop outside the body). A male reaches sexual maturity at 18 months and for females, it is 24 months. Their mating season usually starts in September and continues through December and takes place on land. Males gather on the coasts of small islands in high tide and look for a female to mate with. Females are larger and slower than males, so the male snake chases a female and entwines with her. They align their bodies with each other and contract rhythmically to produce Caudocephalic waves. Their mating process lasts for around two hours, however, the snakes remain interwined for a few days to follow. The female then lays around four to 20 eggs per clutch and it takes the hatchlings about four to five months to come out.

What is their conservation status?

The International Union for Conservation of Nature (IUCN) has classified banded sea kraits with a stable increasing population and they are in the Least Concern category. The threats they face are from predators like sharks, big fish, climate change, and pollution.
